  • Publication number: 20240395266
    Abstract: An audio watermark processing method includes: obtaining input audio; segmenting the input audio, to obtain audio segments; determining original frequency domain coefficients for the audio segments; obtaining embedding information including watermark information and mark information for positioning the watermark information; determining, based on the embedding information, adjustment information corresponding to a first original frequency domain coefficient of a first audio segment of the audio segments; performing an inverse frequency domain transformation on the adjustment information, to obtain a superimposing segment corresponding to the first audio segment; superimposing the first audio segment and a first superimposing segment, to obtain a target audio segment; obtaining target audio segments, embedded with the watermark information; and outputting target audio including the target audio segments.

  • Publication number: 20050171681
    Abstract: A kind of method and system for preventing rear end collision of vehicles are intended to apply to the vehicles equipped with the electric fuel injection system. By using a fuel-decreasing pre-warning electric control unit standing for PW-ECU, the throttle value D of the engine can be obtained through sampling from the throttle sensor 1 of the electric fuel injection system in real time. Do time differential operation to the throttle value D to get the throttle speed value Rt, then comparing the throttle speed value Rt with a preset fuel-decreasing pre-warning value Rp. If Rt equal to or exceed the preset value Rp when the engine decreases the fuel, the pre-warning devices 7 driven by PW-ECU will send out the pre-warning signals to the following vehicles. Therefore we can realize preventing rear end collision of the vehicles by the fuel-decreasing pre-warning method. At same time we provide a system for preventing rear end collision of the vehicles by the fuel-decreasing pre-warning method.
